AUTOMATIC ICE DUMP.

Application filed February 12,- 1923. `Serial No. 6181589.

To all whom t may concern:

Be it known that l, LOUIS P. Reiss, a

citizen of the United States, and resident of the city of Mattoon,county of Coles, and State of Illinois, have invented certain new anduseful Improvements in Automatic Ice lhunps, of which the following is aspecification containing a full, clear, and eXact description, referencebeing had to the accompanying drawings, forming a part thereof.

'Myinvention relates to improvements'in automatic ice dumps and has forits primary object an ice dump for use in ice storage houses which willpermit the delivery of one cake of ice at a time, the dump returningautomatically and being charged with a fresh piece of ice.

A furtherobject is to construct an automatic ice dump which is soconstructed as to permit practically no air to enter an ice storagehouse while ice is being removed therefrom. My device is particularlyintended for the retail department of large are served with pieces ofice already cut to retail dealers. Heretofore the ice has been deliveredyto the retail platform through an ordinary door which, when a rush wason, was almost continuously open thus allowing a great deal of warm airto enter the storage house and .consequently causing quite a loss of icedue to melting. My improved ice dump eliminates all this by cutting downage house to a minimum.

In the construction of my device 15 represents the wall of an ice house,this wall is provided with an opening in which is located a frameconsisting of side members 16, a sill 17, and a top 18, secured to thesill 17 are pivot blocks 19, these pivot blocks are provided with abearing 20 which is circular 7 and which is secured in the sides 16 ofthe frame. The upper portion of that part of the pivot blocks 19 whichextends beyond the frame 16 is cut away so as to leave only asemi-circular bearing 21, these pivot bearings eXtend partially acrossthe frame and the space between these blocks is filled in with a fillerblock 22 which is likewise provided with a semi-circular recess.l/Vithin the blocks 19 are placed pivots 23 which have a circular end 24which is designed to lit in Y the bearing 20, the remainder of the pivotis provided with a V shaped cut 25 in which the door plates 26 and 27extend, these plates are-secured to the pivots 23 by means of screws orbolts 28. Secured to the door plates 26 and 2 7 are rails or strips 29,these strips are firmly secured to the plates and are provided with acurved portion 30 which allows ready sliding of the blocks of ice. Thedoor plates have secured adjacent their side edges angle irons 31 whichact as a guide for the blocks of ice, these angle .irons are adapted tocontact with weather strips 32 which are secured to the frame and are soarranged that when the door is closed the angle irons carried by theVplate 26 will con` tact with one set and prevent the entrance of air,while, when the door is opened the angle irons carried bythe plate 27will contact with the other-'strips and prevent the entrance of air.frame is a bar 33 to which pins 34 are secured, these pins projectthrough the pin openings 35 formed in the plate 27, adjacent the pinopenings 35 are folding stops 36, these stops consist of two members`pivotally Secured to the side of the secured together, one member issecuneljv fastened to the plate 27 while the other member is free toraise and assume an almost vertical position when the pins 34 passthrough the pin openings 35, the free member is also permitted to swingdown and cover the openings 35 when the dump is operated and prevent thepassa-ge of air through said openings. Secured to the under side of theplate 27 and along its rear edge is a eounteriveight 37, thiscounterweight is adapted to come in contact with the L shaped stop 38which is carried by a pivoted lever 39, this lever is provided with a,counterweight 40 which permits the stop 38 to move upwardly when thedump is operated; the stop 38 is adjacent the lower end of the skid orchute 41 down which the blocks of ice to be delivered slide in acontinuous stream. The plate 26 is preferably provided along its topedge with an angle iron 42 which is for the purpose of stiffening thatpart of the door. The plate 26 has also attached thereto, a handle 43 bymeans of which the dump can be operated.

The assembling and operation of my device is as follows:-

In the construction of the frame the sides 16 are provided with suitableopenings so as to permit` the insertion of the ends of the pivot blocks19, these pivot blocks are then bolted down and the insertion 22 placedin position, the pivots 23 are next placed in position and then theliller pivot 44 is placed in the filler block 22, the filler pivot 44 isprovided with a V groove corresponding to the V groove 25, the plates 26and 27 are placed within the V grooves and secured by the bolts 28, theslides 3() and angle irons 31 having been previously secured inposition, the dump is now ready to operate. Upon release of the door itassumes the position shown in Fig. l with the free ends of the foldingstops projecting upward and being held in thatposition by means of thepins 34, a quantity of ice is then placed on the slides 41 and allowedto slide down; one block will come to rest against the folding stops butproject over the end of the door sufficiently to still rest on the skid.This projection, however, is not sufficient to cause the cake of ice tot-ilt backward when the dump is operated. When it is desired to remove acake of ice from the storage house, the handle 43 is pulled down, thiscauses the dump to rock, lifting with it a caire of ice and at the sainetime the stop 38 .is raised by means of the lever 39 and counterweight40 sueiently high to engage the following cake of ice before the foldingstops have fallen downward, this releases the cake of ice on the dump,as soon as the folding stops fall forward, the calze of ice slides onthe strips 29 out through the opening and on to the delivery platform46. During this time the plate 2T has been resting against the rearweather strips and preventing the entrance of outside air. As soon asthe cake of ice is removed from the forward part of the dump, thecounterweight immediately brings it back, this bringing backsimultaneously raises the folding stops 36 and lowers the stop 38 andallows a fresh cake of ice to come on to the dump.

1When it is desired to remove my dump for any purpose, the same can bereadily done by removing the bolts 28 then removing the dump after whichthe filler pivot 44 is first removed and then the pivots 23 can beremoved frein the fra-me. By this construction not only is an air tightpivot made, but the device can be installed after the building has beenbuilt, thus obviating the necessity of either building in the device orremoving a portion of the walls for installation.

Having fully described my invention what l claim is 1. An ice dumpcomprising a pair of door plates, a pivot secured to said plates, pivotblocks for supporting said pivot, strips secured to said plates, acounterweight secured to one of said plates for returning said dump toits loading position, a handle for operating said dump on the pivot,means carried by one of said plates for limiting the movement of icethereon when the dump Y is in charging position, and a stopautomatically operated by the movement of the dump for preventing themovement of ice while the dump is being tilted.

2. An ice dump comprising in combination with a frame, a plurality ofpivot blocks carried by said frame, a pivot provided intermediate itsends with a l! groove, door plates secured in said groove and extendingin opposite directions, angle irons secured to said door plates adjacentthe sides thereof, rails carried by said door plates, strips carried bythe frame and adapted to contact with the angle irons for making an airtight joint, a handle carried by one of said plates for tilting thedump, a counterweight carried by the other plate for returning the dumpto its original position, pins carried by the frame and adapted toproject througi one of said plates, folding stops secured to saidV plateadjacent the pins whereby openings in said plate may be closed when thedump is tilted, and a stop automatically operated by the door forpreventing more than one piece of ice lodging on the dump at a time.

3. An ice dump comprising a pivoted member composed of two plates, railsearried by said plates, folding stops carried by one of said plates,means for elevating said stops when the dump is in charging position, ahandle for operating said dump, and l means for automatically returningand holding the dump in charging position after the same has beenemptied.

4f. An ice dump comprising a pivoted member composed of two platesarranged at an angle to each other adapted to be moved into charging anddischarging position, said plates so arranged as to close the deliveryopening in an ice storage house Whether the 10 dump is in charging ordischarging position thereby preventing the entrance of outside air,stops carried by said dump for limiting the initial movement of icethereon, and means automatically controlled by said dump whereby ice maybe delivered to said dump only when in charging position.

In testimony whereof, I have signed my name to this specification.

LOUIS P. REISS.
